Cellulose acetate (CA) membranes exhibit low protein binding capacity, high thermal stability and high physical strength.
These properties make CA membranes suitable for the high-pressure filtration of aqueous and alcoholic media.
Filter surface – Plain
Pore sizes (µm) – 0.22, 0.45, 0.8, 1.2, 3, 10
Diameters (mm) – 25, 47, 142, 293
Wettability – Hydrophilic
Heat stability – Maintains integrity after autoclaving – 121 °C for 30 minutes
Non-sterile membranes – Autoclavable for 30 minutes at 121 °C
Sterile membranes – Sterilized by Ethylene Oxide (EO)
Non-sterile membranes – Bulk-packed 100 membranes per box
Sterile membranes – Individually packed 100 membranes per box
